Refrigerating Whipped Ganache

I'm sorry if this question has been asked before but I didn't find any answers while doing a search.

I'm making a chocolate cake with whipped ganache for Christmas Eve. Because I'm going to be busy and pressed for time to complete this cake, I would like to prepare as much in advance as possible. I was wondering if it was okay to refrigerate whipped ganache for 3-4 days or refrigerate ganache for 3-4 days and then whip right before use.

I know ganache gets really hard if put in the fridge for too long so I don't want to ruin any and have to chop up more chocolate!

You can also freeze it. I don't usually whip my ganache but I freeze ganache all the time and then just bring it back to temp. I especially like this with a 1 to 1 ratio because if I bring it back to temp on the counter (not the microwave) it's a great piping consistency.

Thanks for the tips! So it sounds like I will be able to refrigerate it or freeze it. If I keep it as a ganache, do I need to let it warm to room temp before whipping or whip when chilled? I'm hearing different things from different sources. Some say it needs to be really cold otherwise it will curdle and some say to whip at room temp.
